DIPPER.

Application filed August 17, 1925.

This invention relates to a dipper and aims for its principal object t provide a dipper which may be submerged in a liquid for removing the same to a predetermined level without creating a. material distur'bance of the liquid.

The invention further comprehends a dipper, the body or bowl of which is capable of adjustment to vary its capacity.

The invention more specically conteniplates a dipper body or bowl in which the bottom is laterallyswingable from a closed to an opened relation to allow for the passage of the body through the liquid with the least possible disturbance after which said bottom is swingable to a closed relation for trapping and removing the liquid within the body.

The invention further comprehends means carried by the dipper handle and operatively connected with the bottom for effecting the swinging move-ment of the same to its closed and opened relations to the dipper bod The invention furthermore embodies a dipper which is comparatively7 simple in its construction and mode of operation, inexpensive to manufacture, and e'tiicient in its purpose. Y

Vith the above recited and other objects in view, the invention is exemplified in the accompanying drawings, the following description and the appended claims, but it is understood that embodiments other than those actually disclosed which fall within the scope of the. appended claims, may be resorted to when found expedient.

In the drawings- Figure 1 is a vertical sectional view through a dipper constructed in accordance with the invention, illustrating the bottom in opened relation to the dipper body;

Fig. 2 is a fragmentary elevation of the upper end of the dipper handle;

F ig. 3 is a horizontal sectional view taken approximately on the line 3-3 of Fig. 1;

Fig. 4 is a similar view taken approximately on the line 4 4 of Fig. 1;

Fig. 5 is a horizontal sectional view taken approximately on the line 5-5 of Fig. 1;

Fig. 6 is a vertical fragmentary view taken approximately on the line 6 6 of Fig. 1;

Fig. 7 is a side view of the dipper body.

Referring to the drawings by characters of reference, 10 designates a substantially cylindrical dipper body, whichis attached to Serial No. 56,790.

the lower end of the handle 11. rEhe dipper body is provided with a semi-annular slot 12 adjacent its lower end to accommodate a laterally swingable bottom 13 secured to the lower end of a rotary shaft 14 extending through a bearing lug 15 at the lower end of the handle 11. The bottom 13 is provided with a marginal semi-annular iiange 16, which is adapted to impinge against the side wall of the dipper body adjacent the slot 12 to assist in sealing the bottom against leakage when the bottom is in closed relation to the body. The shaft 14 extends through a second vertically spaced bearing lug 17 and is formed with an enlarged upper terminal 18 having a squared bore or soclret 19 axially thereof. At the upper end or extremity of the handle 11, a finger ring 20 is secured through which a stem 21 extends' downwardly, the stem being provided at its upper end with a manipulating head 22, between which and the lower end of the ring is interposed a coil expansion spring 23. The stem which is slidable vertically through the ring is swiveled at its lower end to a member 24, which is provided with external spiral grooves and movable through a stationary lug 26 having` complementary spiral ribs 27 engaging the grooves 25, whereby downward movement of the member 24 through the lug 26 sets up a turning movement of said member. The member is provided with an axially projecting squared extension 28, which is received by the squared bore 19 of the head 18, whereby downward pressure exerted on the manipulating head or button 22 effects a turningl movement of the member 24 in one direction and a consequent turning movement of the shaft 14 and bottom 13, for swinging said bottom 13 laterally to an open condition, as illustrated in Figs. 1 and 5. Then the head 22 is released, the spring functions to draw the member 24 in an upward direction effecting a reverse or retrograde turning movement of the same and consequent retrograde turning movement of the shaft 14 to swing the bottom 13 to its normally closed relation with the dipper body 10.

1n order to provide means for adjusting or regulating the capacity of the dipper body 10, it is reduced in diameter at its upper end as at 29, to receive the enlarged lower end 30 of a ring 31 having a similar reduced upper end 32 with which other similarly formedrings 3l may be associated to increase the depth and capacity of the dipper.

In use, when it is desired to remove liquid from Within a receptacle or container to a predetermined level Without materially disturbina` the liquid, the user depresses the head to swing` the bottom 1.3 to an opened relation to the body l0, which permits of the subinersion into and passage of the dipper bod v through the liquid Without inaterialliY disturbing the same. After the dip per hodv has been subn'iergjed to the proper depthl` the head 22 is released to allenv the spring' to return the dipper bottom 13 to a closed relation for trapping and removing)` the liquid vfithin the body.

W'hat is claimed is:

l. A dipper comprising a cylindrical open ended body, a handle connected therewith at its loiver end, a semi-annular slotted portion at the lovver end of said dipper body, a vertical shaft rotatably mounted on the handle, a bottom secured thereto for lateral swinging movement through the slotted portion respectively to closed or open relation with respect to the body, and ieans carried by the upper end of the handle for effecting swinging movements of said bottom in opposite directions, said means comprising an axially movable threaded element handleT a bottom secured thereto 'For lateral swinging movement through the slotted portien respeetiveliv to elo-"ed or open relation ivith res lect to the body, and ine-ns carried bj" the upper end ol. the handle tor effecting; up."

site directions said means comprisingr an Xially movable threaded element having;r si ined connection with the upper end oi the shaftv` a eoniplementarf,v threaded bearing therefor, a push rod extendingr through the upper end of the clipper handle and swivelled to said element, a head at the upper end ot the puso rod, and a springinterposed respectively between the head and the upper end ot the dipper `for normally movingr the push rod in a direction to eliieet the closing ot the bottoni.
